Directions: Read and analyze each item. Circle the letter of the correct answer, 1. If the sample size is 45, what test statistic will you use? A. z-test C. population mean B. t-test D. population standard deviation 2. Which is the correct step in solving for the test statistic value? 1. Simplify. Il. Identify the given. Ill. Substitute the values to the formula. IV. Write the computing formula. A. I, II, III, IV C. II, IV, III, I B. IV, I, III, II D. III, IV, I, II 3. What test statistic will you use if the sample size is less than 30? A. z-test C. sample mean B. t-test D. sample standard deviation For nos. 4-5, refer to the problem below: Given: He:p - 6.2 Ha:H x 6.2 The study has a sample mean of 3.4 and a standard deviation of 4 conducted to 15 respondents. Use a = 0.01. 4. What test statistic will you use to solve the test statistic value? A. z-test C. standard deviation B. t-test D. sample standard deviation 5. What is the computed value?
